Mimecast Outage: Email Resilience Firm Suffers “Service Disruption”

"Customers are likely to see messages being deferred by the Mimecast MTA'

By CBR Staff Writer

Mimecast, a company that specialises in email continuity and resilience, said today it is suffering a service outage – and initially proceeded to point those affected to an updates page that was also unavailable.

The company, which claims to have 296 billion emails under management, said at 16:30 BST: “Mimecast can confirm that we are investigating a service disruption that may result in messages being deferred by our MTAs for US-hosted customers.

It added: “Additionally, customers may intermittently not be able to access Mimecast applications or links protected by our Web Security or TTP services.  We are continuing to investigate and will post further updates here.”

The company drew immediate flak from users on social media after posting its initial status update to its Mimecaster Central Community – which was also down.

The company soon corrected this, but users were quick to point out that the company needs a separate public status page. 

Mimecast describes its raison d’être as to “mitigate the significant business disruption that email failure or downtime causes.” It provides a service that allows email continuity for Microsoft Outlook and other email users.

Computer Business Review has contacted the company for further information on the cause of the outage, which it first reported at 16:10 BST.

In an 17:00 BST update the company added: “While email traffic is being processed, customers are likely to see messages being deferred by the Mimecast MTA’s [message transfer agents], and our applications and services may be intermittently unavailable.  We apologize for the inconvenience and are working to resolve this behavior.”
